A man wearing a Gator-style ski mask has been breaking into the rooms of Boston College students to watch them sleep or to tickle their feet, police said on Wednesday.

Calling the creepy home invasions no laughing matter, Sergeant Michael O'Hara revealed that there have been at least 10 reports of the Boston Tickler, with three on one night in April alone - and his victims appear to have all been men.

Described as a 5-foot-8-inch black male of unknown age wearing a hoodie and disturbing ski mask, the tickler has been reported over the past two years in suburban Boston and some victims reported that the man has watched them through their windows as he committed a sex act.

'This is no myth,' said Sergeant Michael O’Hara, community service officer for Allston and Brighton to Boston.com. 'It’s happening.'

Boston college junior, Teddy Raddell said that he woke with a start at 5am on a Sunday in October because he heard someone thundering down the stairs in his shared student accommodation.

'I thought my roommate had fallen down the steps,' said Raddell, 'but then he started yelling. I got up and he said that he had woken up to someone touching his feet.'

'The guy didn’t take anything and there were laptops and wallets out in the main room,' said Raddell.

Daniel Marenzi, a Boston College junior said that he woke up on Sunday in October to feel his feet being tickled.

'I thought my friend was just trying to annoy me, but I soon realized it wasn’t anyone I knew,' said Marenzi.
